Embodiment Construction

[0025] This embodiment proposes a method for implementing a service virtual port in a GPON-OLT system. The service virtual port is based on GEMPORT to realize the identification of service data flow, and transparently transmits GEMPORT information to SWITCH through PON MAC, which can be established in the entire GPON system Create an end-to-end business data flow channel.

[0026] refer to Figure 1~3 , figure 1 It is a schematic diagram of the method for realizing the service virtual port in the GPON-OLT system of the present invention; figure 2 It is a flow chart of the method for realizing the service virtual port in the GPON-OLT system of the present invention; image 3 It is the Ethernet frame VLAN marking rule of the present invention. The GPON-OLT system includes a SWITCH module and a PON MAC module. In this embodiment, the method for implementing a service virtual port in the GPON-OLT system is as follows:

Abstract

The invention discloses a method for achieving a virtual business interface in a GPON-OLT system. The method comprises the steps as follows: a PON MAN module records mapping table items between GEM streams and Ethernet frames carrying user business according to data stream characteristics of a GEM stream, and then inserts a layer of a VLAN ID (recorded as SPVLAN) that is uniquely determined by anONT ID and a GEMPORT into the Ethernet frame; then the Ethernet frame with the SPVLAN is sent to a SWTICH module; when data is transmitted in a downlink, the PON MAC module finds the corresponding downlink GEM stream according to the mapping table items after removing the SPVLAN in the Ethernet frame; the SWITCH module receives the uplink Ethernet frame with the SPVLAN and achieving uplink streamlimiting management based on the GEMPORT, then removes the SPVLAN, then sends the uplink Ethernet frame to an upper joint port after completing VLAN translation, and meanwhile stores a mapping relation table of uplink Ethernet frames identifiers and the SPVLAN; and when the data is transmitted in the downlink, the SWITHC module receives the Ethernet frame from the upper switch or a public network,achieves downlink flow management according to the mapping relation table of the Ethernet frame identifiers and the SPVLAN after completing VLAN translation, and then sends the message to the PON MACmodule.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing a service virtual port in a GPON-OLT system. Background technique [0002] Most commercial GPON-OLT systems currently on the market adopt the hardware architecture of cascading SWITCH modules and PON MAC modules, and the business data flow is transparently transmitted between the SWITCH chip and the PON MAC chip. Among them, the SWITCH chip is responsible for the VLAN translation and forwarding logic of the service data flow, and the PON MAC chip is responsible for establishing the service data flow mapping between it and the terminal equipment ONT. The functions of the SWITCH module and the PON MAC module in the GPON-OLT system are relatively independent, and the interface of the two functional modules cannot perform unique identification and speed limit management on the service data flow within the system. The high-end GPON-OLT system uses proprie...
